Interpretive Summary: The amazing flavor and texture in strawberries is caused by a complex balance of numerous sugars and aromatic compounds. One of the most important aromatic compounds contributing to the flavor we have come to love in strawberries is mesifurane. Mesifurane produces a sweet sherry-like aroma and increases in concentration as the strawberry ripens. We describe a DNA test that predicts the presence of the gene responsible for mesifurane production in strawberry fruit.

Technical Abstract: The amazing flavor and texture in strawberries is caused by a complex balance of numerous sugars and aromatic compounds. One of the most important aromatic compounds contributing to the flavor we have come to love in strawberries is mesifurane. Mesifurane produces a sweet sherry-like aroma and increases in concentration as the strawberry ripens. Mesifurane production in cultivated strawberries is greatly influenced by the gene FaOMT. The sequence of FaOMT has been well characterized, allowing scientists to study the gene’s function. Allelic variation within the gene’s promoter sequence (regulating gene expression) effectively turn the gene on or off. Mesifurane is not present in the berry unless the gene is turned on. The DNA test FaOMT-SI/NO was developed to identify which alleles are present in any strawberry individual.
